As you also can see from the featured image, the kite’s sail is built up by dacron ribbons. I had a suspicion these ribbons could start to flutter in the stronger winds. I was right.
Actually it wasn’t as bad as I had feared, but definitely an issue to address. In addition it seems like the LE is a bit too soft. It bends quite a bit thus deforming the shape of the kite/sail making the ribbons even looser and more prone to flutter.
But first things first. I have an idea for stabilising the ‘sail’; to add two vertical (more or less) narrower ribbons on each wing half. Hopefully this will prevent the flutter of the horizontal ribbons.
I guess replacing the current LE with a stiffer one will improve the kite’s flying characteristics.
The next step is to tweak the bridle a little. First of all I will move the outer bridle connections from the end caps to the frame, a distance of approximately 4cm for each wing tip. Another little tweak to reduce the bending of the LE.
I might do some more bridle tweaks too, but I will not do this before I see the effect of my other remedies.
…and as mentioned in another post, this is an experiment! …and I’m learning!
